Frequently Asked Questions

Does my JSON leave the browser?

No. All formatting, minification, and validation happens locally in your browser using JavaScript. Your data is never sent to any server.

What indentation options are available?

The formatter uses 2-space indentation by default, which is the most common convention. The minify option removes all whitespace to produce the smallest possible output.

Can I validate JSON without formatting it?

Yes. The validate action checks syntax and reports the exact line and column of any error without modifying the input. Use this when you want to confirm validity without changing the formatting.
